Hello,
I have downloaded the EZNEC 4.0 (demo version) on my Windows XP laptop.
But I can't seem to install it. It's giving the following error:

"C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for
running MS-DOS and Microsoft Windows applications. Choose 'Close'
to terminate the application."

Can you please help me with this?

Thanks!
